HUB-ATTACHING DEVICE.

SPECIFICATION forming part of Letters Patent N 0. 431,187, dated July 1,1890. Application filed April 29, 1890- Serial No. 349,910. (No model.)

To all 1071/0772 it may concern:

Be it known that I, MARSHAL T. FOSTER, of Madison, in the county ofGreenwood and State of Kansas, have invented a certain new and usefulImprovement 111 Devices for Attaching Vehicle-Hubs to Axles, of whichthe following is a specification, reference being had to theaccompanying drawings.

My invention relates to hub-attaching devices of that class in which theaxle is provided with a shoulder which sets into the box, and a followersliding loosely on the axle and screwing into the rear end of thebox,instead of a nut upon the outer end of the axle.

The object ofmy invention is to provide a secure means of attaching awheel to its axle, so constructed that dust, water, and every otherinjurious substance will be absolutely excluded, and at the same time Iprovide means for taking up any wear that may occur between the shoulderon the axle and the box.

In the accompanying drawings, Figure 1 is a central vertical section ofa hub and axle secured together by my invention. Fig. 2 is an elevationof the inner end of the hub, and Fig. 3 is a detached view of the wrenchfor operating the nut.

Referring to the letters upon the drawings, A indicates an ordinary hubprovided with a box B, which is internally screw-threaded at its outerend to receive the screw O, which passes through an orifice in thecoveringplate D and is adapted to hold the box securely in itsplace inthe hub. The box is At the inner end of the box is an enlarged apertureinternally screw-threaded through part of its length and adapted to seatthe shoulder F,-

axle.

G indicates a headless nut which fits close around the axle, but may beslipped longitudinally on it, and is adapted to be screwed into theaperture in the inner end of the box and against the shoulder F. Anyconvenient means may be provided for operating this nut for instance, atwo-pointed wrench l-I, adapted to take into the holes I in the end ofthe nut.

The principal advantage of the nut which I have described is that it ismade without a head and may be sunk entirely into the end of the box. Bythis means it may be securely fastened in place and prevented from beingdislocated by striking against any outside object; but its specialutility is that by reason of its peculiar construction it can beadjusted to compensate for any wear which may occur between the parts.

WVhat I claim is In a hub-attaching device, the combination, with thebox B, bored out to receive the axle, closed at its outer end andprovided at its inner end with an enlarged opening having internalscrew-threads, as described, of the axle having a shoulder F, and aheadless nut adapted to be screwed into the ends of the box against theshoulder F, which is seated in the bottom of the enlarged opening tosecure the hub in place, said enlarged opening being of equal diameterthroughout its entire length, so that the headless nut may be screweddown against the shoulder to take up wear as fast as it occurs,substantially as set forth.

In testimony of all which I have hereunto subscribed my name.
